To all whom t may concern: Y

Be it 4known that I, GEORGE F. M-INNIS, a citizen Aof the United States,-residing at lChicago, in the county of Cook and 'State of Illinois, have invented certain new and useful Improvements in Anchors tor VVind-ow- Vashers Belts, of which the following is'a specilication. v s

' vin-vention vrelates to improvements Tin anchors and more particularly to an anchor for attachment to a stone or brick wafll, the anchor head being arranged for engagement by the Ksafety ela-sp of a win-dow cleansers harness.

ne of the Aobjects of -my invention is =to provide such an anchor for mounting -upon the reveal of 4a windowV-openin-g with the body Vpart of the anchor extendingthroug'h and into engagement with Sthe second layer of brickzor stone. Y f

Another object of my invention is the provision of such an anchor which 1may be firmly Aand rigidly locked in position, is not liable to be pulled out, and at all times retains a rm grip upon the wall even though fthe mortar in vwhich itis embedded should become loose or cracked. I Y

Still other and further Yobjects will become readily apparent to those skilled -in the art from a consideration Aof the following description and drawings, wherein*` Figure l is a side elevation 4of a portion of a building adjacent the window casing showing -my improved anchor in place.

Fig. 2 is a plan view of my V'improved anchor showing the manner of mounting'the same in the wall.

Fig. 3 is a perspective view of the anchor.

Fig. 4 is a front elevation of an improved clip for engagement with the anchor.

Fig. 5 is a vertical sectional view through the clip shown in Fig. 4.

Fig. 6 is a side elevation of a portion of a building showing a modified form of anchor in place.

Fig. 7 is a plan view of the modied form of anchor showing the manner of embedding the same in a wall, and

Fig. 8 is a perspective view of the anchor illustrated in Figs. 6 and 7.

It is common practice for window cleaners when working outside of a building to wear a waist encircling belt to which a rope is secured with its ends supplied with clips for engagement with fastening devices secured to the wallll of the 'buildin-g or to the window casing, ait each `side of the window. These .anchoring devices must, of necessity, be amply strong .to withstand :the weight ofa `man in the event :the cleanershoulld lose his footing and slip over 'the window ledge. Beside the necessity of providing .materiall of vample strength and size, it is'also essential that :such devices be `Vfirmly anchored in the lwalil. iln fpractice 'it is 'found desirable 1n many instances to -position the anchor hea-d yon the reveal aft each side yof the win dowwrame rather than on. the .outer Atalee-of the wall where they are Ymore conspicuous and somewhat Amore difficult for the `cleaner to reach. This is :particularlydesirable in buildings faced with terra cotta and against which the anchors would stand .out con.n spicuously and impair the neat smooth ap,- pearance yof the' structure.

In the two embodiments of my invention illustrated 'in the drawings' have provided an anchor, fthe head ,of which :is arranged for presentation on the reveal formed/between the outer acefof :the wall and window casing. rlhe anchor is so arranged thatit projects from this-point within thewall past -the embedded edge .of the windo-w :casing rand into engagement with the rear tace uof thesecond tier vof bricks.- n

Referring more particularly to ythe form of device illustrated in Figs. 1 .to inclusive, -the numeral 10 indicates the vertica'l'lyelon- `'gated-head 4ot an anchor adapted/to overlie J*the surface of the bricks in the reveal land trom the outer lface of which projects the vertically spaced :apart flugs 'll '.with their :enlarged heads 12 for engagement with Ithe window washers safety clip indicated in general bythe numeral 13. rom the cienrtral portion of the rear face of the head 10 I have extended a dat bar 14 tapering gradually from its widest portion adjacent the head to its end portion 15, the eXtreme end being headed or enlarged vertically, as at b y the numeral 17 to permit it to pass back of the embedded corner of a window casing 18. The rearwardly extending end portion of the bar which is considerably narrower than the front portion is substantially straight and lies at an angle to the face of the wall to position the head 16 in the mortar 19 lying between the second layer of brick 20 and the third layer 21. The body of the bar 14 lies in the mortar between the upper surfaces of brick 20-22-23 and the bottom surfaces of the course of bricks immediately thereabove. The head 16 is of a vertical width considerably greater than the thickness of the mortar between two courses of bricks so that it overlies the rear edges of two adjacent courses of bricks in the second layer. The engagement between the headedy end at the rear of the bar 14 and the second layer of brick tend always to draw the brick 23 and the one immediately thereabove over against the window casing instead of pullingv it outwardly as would be the` case if the anchor extended straight in from the outer face of the wali.

In Figs. 6 to 8, I have illustrated a modified form which the invention may take and in which the flat bar indicated in general by the numeral 30 extends straight backward from the head 10 a distance suicient to pass beyond the edge of the window casing 18 and then turns at right angles, as at 31, inwardly, the outer portion 32 being parallel with the face of the wall and at substantial right angles to the inner portion 33 which extends a distance inwardly in the wall to position the head 16 on the end of the section 32, at the rear face of the second layer of bricks 20. rlhis angled construction permits the mounting of an anchor on the reveal even should the window casing 18 project outwardly as indicated in Fig. 7, a distance sufcient to interfere with the bar of the form illustrated in Figs. 1, 2 and 3. The section 33 of the bar of the modified construction illustrated in Figs. 6, 7 and 8 is of a length ample to pass around the deepest type of window casing and therefore can be used in certain environments where the form shown in Figs. 1, 2 and 3 could not be used. v

In Figs. 4 and 5 have shown a form of clasp for engagement with the head 12 and comprising a vertically slotted body part 40 with spring latch 41 to engage the upper head 12 of the anchor when the slotted portion of the bar 40 is slid over the anchor projection. From the lower end of the body part projects a rope fastener 42 provided with a pair of holes 43, 44 positioned one above the other and arranged to receive and form a half hitch in the rope. The rope indicated in Fig. 1 passes in the lower course 45 up through the lower hole 44 and then bends over, as at 46, and passes .on through the upper hole 43. A bend of rope is then brought over one side and through the loop part 46, as at 48. This tie or half hitch forms an easily shifted connection between the rope and the clasp, the operator being able with one hand to loosen it and shift it from one point to another along the rope.-

VVhereas I have illustrated and described but two embodiments of my invention it is possible that many changes and modificationsmay be made therein without departing from the spirit thereof or the scope of the appended claim.

Having describedmy invention, what' l claim is An anchor for attachment to the reveal in a brick wall between the face of the wall and a window casing, comprising a ver'- tically elongated base to lie against the reveal, a pair of headed projections extending outwardly from the upper and lower portions of the base, and a flat anchor bar ex tending from the rear of the base to lie between adjacent courses of brick, said bar extending away from the reveal to project beyond the outer edge of the casing and its end portion extending away from the face of the wall to a point inside the second layer of brick.

1n testimony whereof 1 hereunto set my hand.

GEORGE r. Minnie.
